    I have a 66" exmark. that until recently cut fine. I have noticed that the quality of cut is horrible and sometimes tall grass is left bent over between second and third blade.
    Also the height of the cut has dropped greatly. where is now when I used to set at 3.5" is now cutting at 2.5"
    any help with this or ideas of whats going on would be great.
    Thank you

    Is this mower new to you? You have the triton deck which a lot of people had cut quality issues with it.

    no the mower is going on around 5-6 seasons with me. I know that the quality of cut with the triton was never comparable to other decks but I don't understand why the height of the cut would change along w/ quality.
    Today the quality of cut was much better with it being dryer out but the height of the cut is still down. when I put it in transport position im getting about 3.75 inches.
    Checked over everything I could think of.
    blades, spindles, pulleys, belts, broken bolts

    Have you checked the pitch of the deck front should be bout .25 inch lower than rear and check your rpm's you should be bout 3600 with blades spinning

    higher you cut at, worst cut you will get
    you get a better cut with deck closer to the ground better suction

    tire pressure? also i changed blades and the offset of the new blades was different. i run a 56 triton it has that little inlay where the bolt head sits it was different on new blades which lowered the cut on mine
